Examples Of Spermatogenesis

Spermatogenesis, the sequence of events occurring in the male testes that produces or develops mature spermatozoa, begins and continues after the male reaches reproductive maturity, which is around 14 years of age, and this process of the production of spermatozoa continues throughout the male’s life. Spermatogenesis occurs under the control of hormones from the brain and from the endocrine cells in the testes, and the lack or insufficiency of one or more of these hormones can cause infertility or subfertility in the individual, making the right amounts of the hormones involved very important.

One of the major hormones involved in the production of spermatozoa is the follicle stimulating hormone, or FSH in short, which is secreted from the

Testosterone is mainly produced by the Leydig cells in the male’s testes but can also be produced in small amounts in the adrenal glands. The hormone testosterone has many functions, and two examples would be signaling the body to make new blood cells and ensuring that the individual’s muscles and bones stay strong during and after puberty, which is especially important as the male would go through several growth spurts during puberty. Starting during foetal development, the hormone testosterone works to initiate the development of the male internal and external reproductive organs. Later in life, testosterone would be essential for the production of spermatozoa. Testosterone is also one of the factors that are linked to many of the changes seen in males during puberty, for example, the sudden increases in height known as growth spurts or bodily and pubic hair growth. Testosterone also regulates the secretion of the luteinizing hormone and the follicle stimulating hormone, which is also required to ensure proper production of spermatozoa, making testosterone a very essential hormone when comes to the production of spermatozoa. In the case of testosterone deficiency during foetal development, the masculinization of the foetus will fail to occur normally, which may give rise to several types of sex development disorders. In another case, where testosterone deficiency occurs during a male’s puberty, a male’s growth may be very slow or have no observable growth spurt. It is important that an individual keeps their testosterone in the right amounts as low levels of testosterone can cause increased body fat, loss of muscle tone, the inability to produce spermatozoa and many other complexities, including infertility; although this mostly just affects ageing men. On the other hand, too much testosterone can lead to infertility or a
